摘要： In a process for producing cyclohexylbenzene, benzene is contacted with hydrogen in the presence of a hydroalkylation catalyst under hydroalkylation conditions effective to form a first effluent stream comprising cyclohexylbenzene, cyclohexane, and benzene. At least a portion of the cyclohexane from the first effluent stream is then contacted with hydrogen in the presence of a dehydrogenation catalyst under dehydrogenation conditions effective to convert at least some of the cyclohexane into benzene contained in a second effluent stream. At least some of the hydrogen is supplied to the process so as to contact the dehydrogenation zone (e.g., the dehydrogenation catalyst) before contacting the hydroalkylation catalyst.

摘要： Provided is a process for producing cyclohexylbenzene, in which a benzene feed stream is subjected to each of the following treatment steps: treating the feed stream with at least one adsorbent and fractionating the feed stream to remove components having a different boiling point than benzene. The treatment steps are carried out in any order and produce a treated benzene feed stream. The treated benzene feed stream is then contacted with hydrogen in the presence of a hydroalkylation catalyst in a hydroalkylation unit under conditions effective to produce a reaction product containing cyclohexylbenzene.
